Ok, now GH has a list up of product (courtesy of Sithclan.net), and includes a list of
basic figures. Of course none of this is confirmed, so we'll have to wait and see...but judging by this listing, I count 44 basic figures (not counting preview). Of course, on that list, there are doubles of Anakin, Obi-Wan, Grievous, Yoda, Palpatine, and Clones (which is ok). Judging by the numbering (which may go by order of release for 2005), if those doubles are legit, they may be coming later in the year. Anyways, click the linky above for the whole she-bang.
Looking at the list again, it looks as if some numbers are missing here and there in the "sequence". Could still be some surprises coming up (not that any of this is confirmed anyways). Going by those numbers, I'm guessing, in collection 1, that figures numbered 46 on will be later in the year, as well as 40-ish on in collection 2 as well. Anyways, the number we have been hearing for launch day is 29, and if you count up what we know from collection 1, and insert 18-42 of collection 2, that comes out about right. A possibility at least.
